INTERNATIONAL ASSOCIATION FOR OBSIDIAN STUDIES

The Proceedings of the 2021 International Obsidian Conference is now available. Click HERE or on the image below to download a copy. 

The poster award at the 2025 Society for American Archaeological Annual Meetings goes to Talia Nishida, Daniel A. Contreras, Oula Seitsonen, Audax Mabulla, Agness Gidna, Katherine M. Grillo, and Mary E. Pendergast for Obsidian Sourcing and Interaction Networks in the Tanzanian Pastoral Neolithic. We'll have more details about the poster soon.

While we continue to maintain the IAOS World Obsidian Source Catalog, our knowledge of obsidian sources outside of the United States and Canada is sometimes incomplete or inaccurate. We would like to invite any regional obsidian source specialists to have a look at the Source Catalog and get back to us (see the email address above) if you spot any problems. We'll be happy to acknowledge your participation and we'd like to thank Dr. Maria Victoria Fernandez for her help in sorting out sources in Patagonia (Argentina and Chile), South America.
